摘要
A chitin-based polyurethane (TRCPU) organogel composed of isophorone diisocyanate (IPDI), polyethylene glycol (PEG) and chitin is shown to undergo a temperature-dependent sal-to-gel transition in polar organic solvents. The soft segments of the prepolymer that originated from the PEG imparted elastomeric and hydrophilic characteristics to the TRCPUs. The hard segments of chitin and IPDI that contained highly polar urethane linkages acted as physical alignment sites and provided lipophilic characteristics for the TRCPUs in the polar organic solvent. The average molecular weight and the degree of acetylation of chitin were determined based on the intrinsic viscosity and solid-state C-13-CP/MAS NMR spectrum. Chitin was incorporated into polyurethane via covalent bonding; the resultant copolymer was an injectable organosol at low temperatures that transformed to a semisolid organogel at approximately 105 degrees C. The TRCPUs were characterized by H-1 NMR, FT-IR and DSC, and the theological behavior of the TRCPU solutions in organic solvents was studied. (C) 2012 Elsevier Ltd. All rights reserved.
